Engineering Contradiction Analysis
1Quantity of substance
If higher frequencies are used for wireless communication, then large bandwidths can be utilized for communication, but beamforming complexities and resource utilization inefficiencies increase
Solution Approach 1:
The patent segments the transmission time interval into multiple allocation units, each independently associated with reference signaling. This segmentation allows for granular resource allocation and beamforming management, reducing overall system complexity while enabling efficient use of large bandwidths at high frequencies.
Solution Approach 2:
The patent introduces flexible modulation and coding schemes that can be dynamically adapted to the number and size of data blocks in each allocation unit. This dynamic adaptation optimizes resource utilization and simplifies beamforming operations by matching transmission parameters to actual data requirements.
2Productivity
If reference signaling is associated with each allocation unit, then resource utilization is optimized, but signaling overhead increases
Solution Approach 1:
The patent changes the parameter of reference signaling association from a fixed pattern to a flexible structure where the number and positioning of reference signaling instances can be adapted based on data block characteristics. This allows optimization of resource utilization while controlling signaling overhead through parameter adjustment.
Solution Approach 2:
The patent applies reference signaling selectively to allocation units based on actual data transmission needs rather than uniformly to all allocation units. This partial application optimizes resource utilization where needed while reducing unnecessary signaling overhead in allocation units without data.
3Productivity
If data blocks are evenly distributed across allocation units, then transmission efficiency is improved, but flexibility in handling varying data sizes is reduced
Solution Approach 1:
The patent employs dynamic modulation and coding schemes that can be adapted to the actual number and size of data blocks in each allocation unit. This dynamic approach maintains transmission efficiency through even distribution while preserving flexibility by adjusting coding parameters to match varying data sizes.
Solution Approach 2:
The patent applies different modulation and coding parameters to different allocation units based on their specific data block characteristics. This local quality approach ensures efficient transmission for each allocation unit while maintaining overall system flexibility to handle varying data sizes across different units.
